A Note From Dr. Winter

“As a veterinarian, I do all I can to provide the most advanced care through my knowledge of Western and Eastern Veterinary Medicine  in both the equine and small animal fields. I believe in compassionate and thorough care of the whole body to treat not just the symptoms, but the underlying root of your pet’s medical issue.”

“It is my goal to utilize both the Eastern and a Western perspective by assessing your pet’s endocrine, cardiovascular and nervous systems, as well as the body’s set of Meridian/Channel lines, its forces of Qi, Blood, Jing, Shen and Jin-ye. In doing so, I’m able to produce a more complete picture what is occurring in your pet’s body to determine what is ultimately causing his or her acute or chronic issue.”

“The most rewarding part for me is the human/animal bond. To see an animal heal, they have their own way of thanking you. To see the owner smile, that’s been earth shattering to me. To be a good veterinarian you have to be compassionate to not just the animal but to the person who owns that animal.”

Why Incorporate Traditional Chinese Medicine Into Your Pet's Treatment Plan

Traditional Chinese Veterinary Medicine (TCVM), although relatively new to the Western world, is a medical system that has been used in China to treat animals for thousands of years.

In Chinese Medicine theory, disease is understood as an imbalance in the body, and diagnosis proceeds through identifying the underlying “pattern” of disharmony. Pattern diagnosis differs from conventional Western medical diagnosis in that it takes into account not only disease signs but how these signs relate to the individual patient. Thus, TCVM practitioners will consider the temperament, sex, age, activity, and environment of an animal along with the animal’s particular disease signs. This approach stems from the belief that the body is as an interconnected system of forces and functions so that disease and disharmony must be examined with respect to the whole patient. For this reason, Chinese Medicine is often regarded as more holistic than conventional Western Medicine.


Dr. Winter offers a holistic approach, eastern and western, to treat acute or chronic symptoms in order to identify the root deficiency that leads to recurrence of symptoms.

Veterinary Acupuncture

Acupuncture may be defined as the stimulation of a specific point on the body with a specific method, resulting in a therapeutic homeostatic effect. This ancient therapy is used to restore the flow of Qi and allow homeostasis to return.

Traditional Chinese Medicine

TCVM aids the veterinarian in diagnosing functional problems in the body. Through an assessment of Yin and Yang, the Eight Principles and the Five Phases, the veterinarian gains a greater awareness of underlying allowing for diagnosis and treatment opportunities.

Most pets are a bit apprehensive upon meeting a veterinarian. But there comes that moment when they realize I’m there to help. That moment when they say thank you with their eyes is why I do what I do.

Any glimpse into the life of an animal quickens our own and makes it so much larger and better in every way.
